Description

Die vorliegende Erfindung betrifft eine Hybridantriebsanordnung für ein Fahrzeug mit einem Antriebsstrang gemäß der im Oberbegriff des Patentanspruches 1 bzw. 8 näher definierten Art.The The present invention relates to a hybrid drive assembly for a vehicle with a drive train according to the in the preamble of claim 1 or 8 defined in more detail Art.

Beispielsweise aus der Druckschrift JP 05038956 ist eine Hybridantriebsanordnung für ein Fahrzeug bekannt. Der Antriebsstrang des Fahrzeuges umfasst einen Verbrennungsmotor, der über eine Kupplung mit einem elektrischen Motor verbunden ist, der als Generator und auch als Antriebsquelle für das Fahrzeug dient. Der Elektromotor ist mit einer Batterie verbunden, die im Motorbetrieb als Energiequelle dienen kann und im Generatorbetrieb aufgeladen wird und als Speicherquelle dient. Der Elektromotor ist über eine weitere Kupplung mit einem Getriebe verbunden, welches entsprechende Übersetzungen bereitstellt, um eine gewünschte Abtriebsdrehzahl an die Antriebswellen des Fahrzeuges abzugeben.For example, from the document JP 05038956 a hybrid drive arrangement for a vehicle is known. The powertrain of the vehicle includes an internal combustion engine that is connected via a clutch to an electric motor that serves as a generator and also as a drive source for the vehicle. The electric motor is connected to a battery, which can serve as an energy source during engine operation and is charged in generator mode and serves as a storage source. The electric motor is connected via a further clutch to a transmission which provides corresponding ratios to deliver a desired output speed to the drive shafts of the vehicle.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Hybridantriebsanordnung der eingangs beschriebenen Gattungen vorzuschlagen, bei der das Antriebskonzept, insbesondere auch das Anfahren des Fahrzeuges, weiter optimiert wird.Of the The present invention is based on the object, a hybrid drive arrangement to propose the genera described in the introduction, in which the Drive concept, in particular the start of the vehicle, is further optimized.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 bzw. 8 gelöst. Weitere vorteilhafte Ausgestaltungen ergeben sich insbesondere aus den jeweiligen Unteransprüchen.These The object is achieved by the features of claim 1 or 8 solved. Further advantageous embodiments emerge in particular from the respective subclaims.

Demnach wird eine Hybridantriebsanordnung für ein Fahrzeug mit einem Antriebsstrang vorgeschlagen, welcher einen Verbrennungsmotor, ein Getriebe mit variabler Übersetzung, zumindest eine antriebsseitig angeordnete elektrische Maschine und ein Anfahrelement umfasst, wobei als Anfahrelement zu mindest ein hydrodynamischer Wandler antriebsseitig des Getriebes angeordnet ist.Therefore is a hybrid drive assembly for a vehicle with a powertrain proposed which an internal combustion engine, a transmission with variable ratio, at least one drive side arranged arranged electrical machine and a starting element, wherein as a starting element to at least one hydrodynamic converter on the drive side the transmission is arranged.

Durch die Verwendung eines nahezu verschleißfreien Anfahrelements in Form eines Wandlers kann ein möglichst wartungsfreier Betrieb des Fahrzeuges realisiert werden. Zudem ergibt sich der Vorteil, dass durch die Ausnutzung der entsprechenden Wandlerkennung eine Anpassung der Motorcharakteristik an die Anforderungen des Abtriebes ermöglicht wird. Beispielsweise sind so genannte Drehmomentüberhöhungen bei der Übertragung des jeweiligen Motormomentes möglich.By the use of a virtually wear-free starting element in the form of a transducer can be as maintenance-free as possible Operation of the vehicle can be realized. In addition, there is the advantage that by the use of the corresponding Wandlerkennung a Adaptation of the engine characteristics to the requirements of the output is possible. For example, so-called torque peaks in the transmission of the respective engine torque possible.

Im Rahmen einer besonders vorteilhaften Ausführungsvariante der vorliegenden Erfindung kann vorgesehen sein, dass der hydrodynamische Wandler zwischen der elektrischen Maschine und dem Getriebe vorgesehen ist. Auf diese Weise kann nicht nur das Motormoment des Verbrennungsmotors sondern auch das Motormoment der elektrischen Maschine über den als Anfahrelement vorgesehenen Wandler übertragen werden. Somit gelten die vorbeschriebenen Vorteile sowohl bei einem rein elektrischen, einem kombinierten oder auch bei einem Antrieb nur durch den Verbrennungsmotor.in the Frame of a particularly advantageous embodiment The present invention can be provided that the hydrodynamic converter is provided between the electric machine and the transmission. In this way, not only the engine torque of the internal combustion engine but also the engine torque of the electric machine be transmitted to the intended as starting element transducer. Thus, the advantages described above apply both to a purely electrical, a combined or even a drive only by the internal combustion engine.

Eine andere Variante der Erfindung kann vorsehen, dass der hydrodynamische Wandler direkt mit der Ausgangswelle des Verbrennungsmotors verbunden ist. Es sind auch andere Anordnungsmöglichkeiten denkbar. Beispielsweise können auch mehrere Wandler vorgesehen sein, so dass jeder Antriebsquelle ein Wandler zugeordnet ist.A another variant of the invention may provide that the hydrodynamic Transducer directly connected to the output shaft of the internal combustion engine is. There are also other arrangement options conceivable. For example, a plurality of transducers may be provided, so that each drive source is associated with a transducer.

Um die Antriebs- bzw. Anfahrmöglichkeiten bei der vorgeschlagenen Hybridantriebsanordnung zu erweitern, kann eine nächste Weiterbildung der Erfindung vorsehen, dass als Anfahrelement und/oder Trennelement eine Kupplung mit dem Antriebsstrang verbunden ist. Die Kupplung kann an beliebigen Stellen im Antriebsstrang angeordnet sein. Bevorzugt kann die Kupplung mit der Ausgangswelle des Verbrennungsmotors verbunden sein. Auf diese Weise kann der abtriebsseitige Bereich von dem Verbrennungsmotor getrennt werden, indem die Kupplung geöffnet wird. Somit ist ein rein elektrischer Antrieb auch bei abgeschaltetem Verbrennungsmotor möglich. Es ist auch denkbar, dass eine Kupplung zusätzlich antriebsseitig und/oder abtriebsseitig des hydrodynamischen Wandlers vorgesehen wird. Die antriebsseitige Anordnung bietet den Vorteil, dass ein elektrischer Antrieb durch das Abtrennen bzw. das Schließen der Kupplung ermöglicht wird. Die abtriebsseitige Anordnung der Kupplung bietet dagegen den Vorteil, dass ein Starten des Verbrennungsmotors durch die elektrische Maschine ermöglicht wird.Around the drive or starting possibilities in the proposed Expanding hybrid drive assembly may be a next Provide development of the invention that as a starting element and / or Separating element is a coupling connected to the drive train. The clutch can be arranged anywhere in the drive train be. Preferably, the coupling with the output shaft of the internal combustion engine be connected. In this way, the output side area be disconnected from the internal combustion engine by opening the clutch becomes. Thus, a purely electric drive is also switched off Internal combustion engine possible. It is also conceivable that one Coupling additionally on the drive side and / or output side of the hydrodynamic converter is provided. The drive side Arrangement offers the advantage that an electric drive through allows the separation or closing of the clutch becomes. The output side arrangement of the clutch offers, however the advantage that starting the internal combustion engine by the electric Machine is enabled.

Da eine Kupplung eine vollständige Trennung des Antriebsstranges im Gegensatz zu dem hydrodynamischen Wandler ermöglicht, kann diese Anordnungsmöglichkeit sinnvoll sein, wenn eine vollständige Abtrennung des Antriebsstranges gewünscht wird.There a clutch a complete separation of the drive train unlike the hydrodynamic converter allows This arrangement option may be useful if a complete separation of the drive train desired becomes.

Die der Erfindung zugrunde liegende Aufgabe wird auch durch eine Hybridantriebsanordnung für ein Fahrzeug mit einem Antriebsstrang gelöst, bei der als Anfahrelement zumindest eine Kupplung und zumindest eine Übersetzungsstufe antriebsseitig des Getriebes angeordnet sind. Auf diese Weise kann nicht nur der Anfahrvorgang optimiert werden, sondern auch die Auslegung der jeweiligen Antriebsmotoren durch die Wahl der Übersetzungsstufe entsprechend verändert werden.The The object underlying the invention is also achieved by a hybrid drive arrangement solved for a vehicle with a drive train, in which as a starting element at least one clutch and at least arranged a translation stage drive side of the transmission are. In this way not only the start-up process can be optimized but also the design of the respective drive motors changed accordingly by the choice of the translation stage become.

Vorzugsweise kann eine Übersetzungsstufe mit einer konstanten Übersetzung verwendet werden. Dazu kann eine Stirnradstufe und/oder Kegelradstufe oder dergleichen eingesetzt werden.Preferably, a translation stage with a constant translation can be used. This can be a spur gear and / or cone wheel step or the like can be used.

Die vorbeschriebenen Anordnungsmöglichkeiten, Ausgestaltungen und Varianten können auch beliebig miteinander kombiniert werden, wobei auch die Anzahl der einzelnen verwendeten Komponenten variiert werden kann.The above-described arrangement options, configurations and variants can also be combined with each other and the number of individual components used varies can be.

An der Abtriebsseite des hydrodynamischen Wandlers 4 ist als Anfahr- und/oder Trennelement die zweite Kupplung 9 angeordnet. Somit kann wieder bei geöffneter Kupplung 9 ein rein elektrischer Antrieb durch die elektrische Maschine 3 ermöglicht werden. Zudem besteht wie auch bei den anderen Ausführungsbeispielen die Möglichkeit, dass das Getriebe 2 in Neutral gestellt wird, so dass auch hier eine Möglichkeit besteht, den Verbrennungsmotor 1 durch die elektrische Maschine 3 zu starten.In 4 shows the second embodiment of the hybrid drive assembly according to the invention, in which the hydrodynamic converter 4 directly with the output shaft 8th of the internal combustion engine 1 connected. At the output side of the hydrodynamic converter 4 is as start-up and / or separating element, the second clutch 9 arranged. Thus, again with the clutch open 9 a purely electric drive through the electric machine 3 be enabled. In addition, as with the other embodiments, there is the possibility that the transmission 2 is set in neutral, so that there is a possibility here, the internal combustion engine 1 through the electric machine 3 to start.

Schließlich zeigt 5 ein drittes Ausführungsbeispiel der Hybridantriebsanordnung, bei dem anstelle des Wandlers 4 als Anfahrelement eine Kupplung 11 vorgesehen ist. Die Kupplung ist mit der Eingangswelle 12 des Getriebes 2 verbunden. Darüber hinaus ist eine Übersetzungsstufe 10 zwischen dem Verbrennungsmotor 1 und der elektrischen Maschine 3 vorgesehen.Finally shows 5 A third embodiment of the hybrid drive assembly, in which instead of the converter 4 as a starting element a clutch 11 is provided. The coupling is with the input shaft 12 of the transmission 2 connected. In addition, a translation level 10 between the internal combustion engine 1 and the electric machine 3 intended.
